The following error is seen in the browser console when trying to use the standalone.js in website.

standalone.js:11 Uncaught (in promise) ReferenceError: regeneratorRuntime is not defined
    at Object.d (standalone.js:11:356755)
    at e.exports [as liHARToK6Script] (standalone.js:11:357262)
    at run ((index):48:36)
    at (index):52:3

This is the code used to create the website

<!DOCTYPE html>
<html lang="en">
<head>
  <title>k6 test</title>
</head>
<body>
    Check the console.
</body>

<script src="standalone.js"></script>
<script>
  async function run () {

    const config = {
      log: {
        entries: [
          {
            request: {
              method: "POST",
              url: "http://test.loadimpact.com/login",
              headers: [
                {
                  "name": "Content-Type",
                  "value": "application/json"
                }
              ],
              postData: {
                "mimeType": "application/json",
                "text": "{\"user\":\"admin\",\"password\":\"123\"}"
              },
            },
          }
        ],
      }
    };

    const { main } = await harToK6.liHARToK6Script(config);
    console.log(main);
  }

  run()
</script>

</html>

I tried both the pre-built standalone.js in the repo and building one myself with the webpack config in the repo.

The text was updated successfully, but these errors were encountered:

Found a work around for the error. Add the following script along with the standalone.js <script src="https://unpkg.com/regenerator-runtime@0.13.1/runtime.js"></script> . It was mentioned in this thread, babel/babel#9849

Example:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>k6 test</title>
</head>
<body>
    Check the console.
</body>

<script src="https://unpkg.com/regenerator-runtime@0.13.1/runtime.js"></script>
<script src="standalone.js"></script>

<script>
  async function run () {

    const config = {
      log: {
        entries: [
          {
            request: {
              method: "POST",
              url: "http://test.loadimpact.com/login",
              headers: [
                {
                  "name": "Content-Type",
                  "value": "application/json"
                }
              ],
              postData: {
                "mimeType": "application/json",
                "text": "{\"user\":\"admin\",\"password\":\"123\"}"
              },
            },
          }
        ],
      }
    };

    const { main } = await harToK6.liHARToK6Script(config);
    console.log(main);
  }

  run()
</script>

</html>

Returns the following to the console:

import { sleep } from 'k6'
import http from 'k6/http'

export const options = {}

export default function main() {
  let response

  response = http.post('http://test.loadimpact.com/login', '{"user":"admin","password":"123"}', {
    headers: {
      'Content-Type': 'application/json',
    },
  })

  // Automatically added sleep
  sleep(1)
}
